As shown in Figure 9 the lower edge of the end walls of the seatbase member 26 are of longitudinally arcuate conguration as shown at 49so that the entire seat structure may be readily rocked forward andbackwardly in the event the weight on the seat is sufi'icient to flexthe springs 3|.

The base 26 of the seat I0 is adapted to be adjusted longitudinally ofthe Vehicle by means of a pair of U-shaped guide members 50 which aredisposed in parallel relation one adjacent each end wall of the seat andare adapted to be xedly secured to the floor of the vehicle. The basemember 26 is provided with a transversely disposed bar 5| having rightangularly disposed opposite end portions 52 on which rollers 53 aresecured by means of pins or bolts 54. The rollers 53 rotatably engagewithin the channel formed by the U-shaped tracks or guide members 50. Inthe present instance, one bar or strip 5| is secured as by fasteningmembers 55 in the form of rivets or the like to the under sides of thesprings 3| as shown in Figures 2 and 3.

The spring supporting pins 34 as shown' inv Figure 4 are preferablycarried by a bracket member 56 which is secured by suitable fasteningdevices to the inner side of an end wall 51 of the base member 26. Inthis manner the pins 34 will be entirely concealed within the base mem-`ber 26.

The seat member l is locked in adjusted position on the supporting rails50 by a pair of releasable locking pins 58 which are slidable in bosses59 carried by a transversely extending bar 60. 'Ihe bar 60 is fixed byymeans of rivets or fastening devicesl 6| 'to the two springs 3| so thatthebar 60 will move with the base 26. The channel member or guide 50 asshown in Figure 2 is provided with a plurality of longitudinally spacedapart openings 62 in which the locking pins 58 are adapted to engage.The two pins 58 which engage the two channels or guide members 50 areoperated simultaneously by means of a pair of links 63 which areconnected at their outer ends to the locking pins 58 and at their innerends to a rotatable plate |54.l The plate 64 is rotatably carried on apivot 65 extending through the bar 66 in substantially the longitudinalcenter of the bar 6U. The plate 64 is provided with an ear 66 having anopening 61 in which one end of contracting spring 68 engages. Theopposite end of the spring 68 is secured to the bar 60 and normallyholds the pins 58 in an extended or locking position. Theplate 64 isprovided with a second ear 69 diametrically opposite from the ear 66 anda releasing rod or member 10 engages through the ear 69 and is extendedbeyond one of the guide members U and is provided with a handle 1| sothat the locking pins 58 may be retracted to a released position inorder to permit the base member 26 to be moved longitudinally of theguide members 5D.

What I claim is:

1. In a seat structure for use in connection with vehicles, a bodilyhorizontally adjustable tiltable resiliently supported basefor a seatmember, a pair of oppositely disposed spaced parallel horizontallyextending stationary outwardly opening channel-shaped guides arrangedbelow said base and provided in their inner sides with spaced openings,a slide bar disposed in transverse relation with respect to and arrangedbelow said base, said bar being slidably mounted on and having dependingend portions opposing the outer sides of said guide, rollers carried bysaid end portions and extending into said guides, a pair of elongatedconcave horizontally disposed multiple leaf springs arranged over andbeim,r secured intermediate their ends to said bar in proximity to saidend portions, said springs having their terminal portions extendingupwardly into said base, rollers carried by said base, arranged over andengageable with the rear terminal portions of said springs, verticallymovable spring controlled spaced coupling rods suspended within and fromsaid base and being pivotally connected at their lower ends to theforward ends of said springs, a supporting bar bodily movable with saidslide bar, and latching means carried by the supporting bar andcorrelating with selective openings of said guides for releasablylocking the base in its horizontally adjusted position.

2. In a seat structure for use in connection with vehicles, a bodilyhorizontally adjustable tiltable resiliently supported base for a seatmember, a pair of oppositely disposed spaced parallel horizontallyextending stationary outwardly opening channel-shaped guides arrangedbelow said base and provided in their inner sides with spaced openings,a slide bar disposed in transverse relation with respect to and arrangedbelow said base, said bar being slidably mounted on and having dependingend portions opposing the outer sides of said guides, rollersv carriedby said end portions and extending into said guides, a pair of elongatedconcave horizontally disposed multiple leaf springs arranged over andbeing secured intermediate their ends to said bar in proximity to saidend portions, said springs having theirterminal portions extendingupwardly into said base, rollers carried by said base, arranged over andengageable with the rear terminalportions of said springs, verticallymovable spring controlled spaced coupling rods suspended within and fromsaid base and being pivotally connected at their lower ends to theforward ends of said springs, a supporting bar bodily movable with saidslide bar, latching means carried by the supporting bar and correlatingwith selective openings of said guides for releasably locking the basein its horizontally adjusted position, means for coupling said rodstogether, and equalizing springs for said rods.

3. In a seat structure for use in connection With vehicles, a pair ofspaced stationary horizontally disposed parallel guides formed withspaced openings, a slide structure slidably mounted on said guides andhaving rollers travelling within the guides, a pair of spacedhorizontally disposed elongated resilient elements of bow-shaped contourarranged over and being fixed intermediate their'ends to said slidestructure, a bodily horizontally adjustable base for a seat member, saidbase being arranged over said guide structure, said elements extendinginto and engaging with the rear of the base, a vertically movable springcontrolled coupling structure suspended in and from said base, means forpivotally connecting the front ends of said elements to the lower end ofthe coupling structure, and means bodily moving with said slidestructure and correlating with selective openings of said guide forreleasably locking the base in its horizontally adjusted position.

4. In a seat structure for use in connection with vehicles, a bodilyhorizontally adjustable base for a seat member, a pair of oppositelydisposed spaced horizontally depending stationary outwardly openingchannel-shaped guides disposed below the base and formed in their innersides with spaced openings, a slide bar disposed at right angles to andslidably mounted on said guides, said slide bar having vdepending endportions opposing the outer sides of said guides, rollers carried .bysaid end portions and extending into said guides, horizontally disposedspaced aligned resilient elements arranged over and being securedintermediate their ends to said bar, said elements having rear terminalportions extending up into and slidably engaging with the rear of saidbase, vertically movable spring controlled coupling rods suspended inand from the front portion of said base, means for pivotally connectingthe forward ends of said elements to the lower ends of said couplingrods, supporting means at the lower portion of the base bodily movingwith said. slide bar and elements, and a latching structure carried bysaid supporting means and correlating with selected openings of saidguides for releasably securing said base in its horizontally adjustableposition.
